Dr. Ryoichi Obitsu, honorary director of Obitsu Medical Center in Japan, has defied aging and illness for decades. At 88, he still works nearly every day, lectures nationwide, and writes extensively—all without a single cold or major disease in 30 years. His approach combines three daily foods, a relaxed attitude toward salt and alcohol, and a purposeful breathing practice that balances the autonomic nervous system.
Three Foods He Eats Every Day
Dr. Obitsu credits much of his vitality to a simple, consistent diet. He does not follow restrictive fads; instead, he prioritizes foods he genuinely enjoys.
Seaweed Tofu Soup – This is his nonnegotiable daily staple. The soup contains kelp, rich in calcium and phosphorus, essential for bone health as we age. He adds extra broth to boost hydration. Remarkably, he reports that his white hair began turning black again after starting this habit—a sign, he says, of the seaweed’s effect on hair health.
Fresh Sashimi – He eats seasonal raw fish almost every day, particularly bonito. During autumn migrations, the fish is at its peak flavor and nutrition. He pairs it with crispy garlic slices for texture. The high-quality protein helps prevent muscle loss and osteoporosis, both critical concerns for older adults.
A Bowl of Rice After Alcohol – Unlike many who avoid carbs in later years, Dr. Obitsu enjoys a light bowl of rice after his evening drink. He prefers seasonal variations such as carrot rice, bamboo shoot rice, or chestnut rice. His philosophy: eat what you want, but in small portions. This satisfies cravings without overloading the body.
What He Avoids—and Why
Dr. Obitsu believes strict dietary rules can backfire. He identifies three common restrictions that he deliberately ignores.
No Extreme Salt Reduction – He argues the body needs salt to function. He recalls a nurse who tried a zero-salt “Gerson therapy” and developed a severe headache by day three. After eating salted kelp, her symptoms vanished. For those who consume too much salt, he suggests simply cutting back the next day rather than eliminating it entirely.
No Complete Alcohol Abstinence – He views moderate drinking as a reward and a relaxation tool. A small amount of alcohol activates the parasympathetic nervous system, promoting calm and aiding digestion. The key is moderation—never excess.
No Forcing Unwanted Foods – Many health advocates recommend raw lettuce for fiber, but Dr. Obitsu calls it “grasshopper food.” Instead, he chooses vegetables he likes, such as stir-fried mushrooms, bitter melon, and cooked greens. Enjoyment, he insists, is essential for the body to absorb nutrients.
A Breathing Technique That Restores Balance
Beyond diet, Dr. Obitsu practices a daily qigong routine called nei gong. This involves slow, deliberate movements synchronized with breathing to enhance circulation, strengthen the legs and hips, and boost natural healing.
He also teaches a simple walking breath method that anyone can do anywhere. The principle: exhalation is more important than inhalation, because exhaling activates the parasympathetic nervous system and calms the body.
The 5-Step Walking Breath:
- Step 1: Walk three steps while exhaling continuously through the nose.
- Step 2: On the fourth step, inhale deeply through the nose.
- Step 3: On the fifth step, repeat from Step 1, maintaining a steady rhythm.
- Repeat for several minutes.
Improper breathing—shallow, rapid inhales—can overstimulate the sympathetic nervous system, leading to issues like insomnia, migraines, palpitations, and fatigue. Dr. Obitsu’s method deliberately shifts the balance toward relaxation.
The Bigger Picture
Dr. Obitsu’s longevity stems not from a single miracle food or exercise, but from a holistic mindset: eat what nourishes you, allow small indulgences, and train your breath to manage stress. His 30-year record without illness suggests that sustainable health habits, built on joy and moderation, may outperform rigid regimens.
For readers interested in adopting similar practices, start with one daily soup, a mindful walk with the breathing pattern, and permission to enjoy your meals without guilt. As always, consult a healthcare professional before making significant changes, especially if you have underlying conditions.
